I strapped the MYZONE on and all of a sudden a box appeared on the TV screen. It had my stats on the screen with my name on top. It was live feed of my heart rate. He told me to excise using the tool he gave me. Each time I would push a little harder, my heart rate increased and the color in the box would change from, blue to green, green to yellow and at the hardest I could go, the box turned red.
